Magnetic Putty: Make your Slime or Putty at Home for Kids
Explanation: In this experiment, the main property is magnetism! The neodymium magnets attract the slime because the slime contains iron filings which are present in the printer toner. Therefore, when the neodymium magnets are brought close to the slime, magnetic repulsion and attractions are produced between the iron filings and the magnet.
The slime is able to hold onto its iron filings by adhesion. Adhesion is the force that holds molecules of different substances together. In addition to adhesion, the slime is bonded together by cohesion, the force that holds molecules of the same substance together. The combination of magnetism, adhesion, and cohesion results in the weird, stretchy noses and tails that appear when you hover the neodymium magnet near the slime!
